STUDIES ON THE COMBINATION OF THE INFLUENCE OF ALCOHOL AND NIGHT FATIGUE

In two series of tests carried out at night (at 21.00, 23.00, 1.00, 3.00 and 5.00 hrs) 38 test subjects, both sober and drunk, were tested with the D-2-test, the Beck equipment and the tachistoscope. It was found that night fatigue causes decreased efficiency, but no conclusion was able to be drawn with regard to potential efficiency decrease resulting from the influence of alcohol combined with night fatigue. /TRRL/
